摘要
A new structured approach to adaptive noise cancelling of non-stationary stochastic signals is given. The divide and conquer method subdivides the problem into a number of sources with a power of 2 and subdivides the solution to smaller problems in a similar fashion to that of an FFT. Hence, with the number of sources 2p, where p is a positive integer, the problem is successively reduced to simpler solutions at each stage of order 2p1. In its basic form, the method uses only multivariable least mean squares (MLMS), ordinary LMS, and second-order statistics.
